Description
Technical field
The utility model belongs to product sensor technical field, particularly a kind of highly reliable high temperature resistant temperature sensor.
Background technology
In prior art; conventional high temperature resistant NTC temperature sensor is that the NTC thermistor 1 ' of glass-encapsulated is welded on high temperature resistant wire 2 '; then the method for filled high-temperature resin 3 ' is fixed on NTC thermistor 1 ' in metal coating shell 4 ' (as shown in Figure 1), makes it can not be subject to extraneous physical impact and damages.
The weak point of above-mentioned technique is: this is high temperature resistant, and NTC temperature sensor serviceability temperature scope is 150～200 ℃, it can not tolerate higher temperature (for example 250 ℃ of above temperature), because for a long time when 250 ℃ or above hot operation,, to the reliability of temperature sensor, there is very large hidden danger in the aging even charing of high-temperature resin 3 ' meeting of filling.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, specifically disclose a kind of highly reliable high temperature resistant temperature sensor, this temperature sensor can be surveyed to higher temperature range, and its detection time is more quick, and good stability, in addition temperature sensor longer service life.
In order to overcome above-mentioned technical purpose, the utility model is realized by following technical scheme:
A kind of highly reliable high temperature resistant temperature sensor described in the utility model; comprise with the metal coating shell of an openend and a blind end and be placed in the NTC glass-encapsulated resistance in metal coating shell; described NTC glass-encapsulated resistance is connected with fire resistant electric wire by conductive metal band; described conductive metal band is placed in metal coating shell, in described metal coating shell, is also filled with insulation high-temperature-resistant micro mist.
As the further improvement of above-mentioned technology, described conductive metal band is conducting copper belt, and described conducting copper belt is fixedly connected with fire resistant electric wire by the mode of riveted joint.
As the further improvement of above-mentioned technology, the openend of described metal coating shell is roll extrusion reducing; The blind end of described metal coating shell is cone-shaped.
In the utility model, described insulation high-temperature-resistant micro mist is ceramic powder or glass dust or metal oxide micro mist, or the potpourri of at least two kinds of materials in above-mentioned substance.
In the utility model, the tolerable temperature scope of described metal coating shell is >=350 ℃, and the temperature resistant range of described fire resistant electric wire is >=350 ℃.
Compared with prior art, the beneficial effects of the utility model are:
(1) highly reliable high temperature resistant temperature sensor described in the utility model, because the method for riveting by conducting copper belt is connected NTC glass-encapsulated resistance with fire resistant electric wire, NTC glass-encapsulated resistance can not come off because of the thawing of scolding tin in more than 260 ℃ temperature, temperature tolerance improves greatly, and product also extends serviceable life;
(2) the utility model is owing to changing filler into insulation high-temperature-resistant micro mist by high-temperature resin, in addition, adopt machine roll extrusion reducing to fire resistant electric wire at metal coating shell aperture end, the reducing of roll extrusion can not dropped insulation high-temperature-resistant micro mist, make like this temperature sensor can be the scope work of 300-350 ℃ and without worrying that the aging or charing of filling material impacts product reliability, good heat conductivity;
(3) the utility model temperature sensor is owing to adopting metal coating shell blind end taper design, and this design can be accelerated the thermal response time of sensor, makes detecting temperature more timely, accurate, and efficiency improves greatly.

Embodiment
As shown in Figure 2; a kind of highly reliable high temperature resistant temperature sensor described in the utility model; comprise with the metal coating shell 1 of an openend 11 and blind end 12 and be placed in the NTC glass-encapsulated resistance 2 in metal coating shell 1; described NTC glass-encapsulated resistance 2 is connected with fire resistant electric wire 4 by conductive metal band 3; described conductive metal band 3 is placed in metal coating shell 1, in described metal coating shell 1, is also filled with insulation high-temperature-resistant micro mist 5.
The openend 11 of described metal coating shell 1 is roll extrusion reducing, and the blind end 12 of described metal coating shell 1 is cone-shaped, and the tolerable temperature scope of described metal coating shell 1 is >=350 ℃, and the temperature resistant range of described fire resistant electric wire 4 is >=350 ℃.
In the utility model, described conductive metal band 3 is conducting copper belt, and this conducting copper belt 3 is fixedly connected with fire resistant electric wire 4 by the mode of riveted joint.Described insulation high-temperature-resistant micro mist 5 is ceramic powder or glass dust or metal oxide micro mist, or the potpourri of at least two kinds of materials in above-mentioned substance.
Below illustrate the manufacturing process of highly reliable high temperature resistant temperature sensor described in the utility model:
(1) first, NTC glass-encapsulated resistance 2 use conductive metal bands 3 (being conducting copper belt) are riveted in fire resistant electric wire 4;
(2) then, NTC glass-encapsulated resistance 2 is inserted to the bottom position (corresponding its blind end 12) of metal coating shell 1;
(3) then, to 1 li, metal coating shell, fill enough insulation high-temperature-resistant micro mists 5;
(4) last; in the openend 11 forward end roll extrusion reducings of metal coating shell 1 to till being adjacent to the line skin of fire resistant electric wire 4; make the insulation high-temperature-resistant micro mist 5 of filling compress fine and close; the effect not dropping to reach insulation high-temperature-resistant micro mist 5, thus highly reliable high temperature resistant temperature sensor manufacturing process completed.
